B. The following special provisions apply:
1. If conduct constituting an element of an offense or a result constituting an element of an offense occurs in two or more counties, trial of the offense may be held in any of the counties concerned; or
2. A person who in one county solicits, aids, abets or attempts to aid another in the planning or commission of an offense in another county may be tried for the offense in either county; or
3. If an offense is committed in transit and it cannot readily be determined in which county the offense was committed, trial of the offense may be held in any county through or over which the transit occurred; or

If the cause of death is inflicted in one county and death ensues out of this state, trial of the offense shall be in the county where the cause was inflicted. If the body of a homicide victim is found in a county, it is presumed that the cause of death was inflicted in that county; or

If an offense has been committed within this state and it cannot readily be determined within which county or counties the commission took place, trial may be held in the county in which the defendant resides or, if the defendant has no fixed residence, in the county in which the defendant is apprehended or to which the defendant is extradited.
